Hi Joe,
Your board looks like one of the interpolator cards from an HP 5370A Universal Time Interval Counter. Do you see an "05370-6xxxx" part number on the board anywhere?

Hi Ed,
I posted a picture at
<
http://home.cfl.rr.com/rigdon14/t-bird/hp-ic.jpg>.
I unplugged the two ICs in the top RH corner and turned them over so that
you can see the bottom and side of the ICs and the heat sink that the IC
normally sits on. There is a depression in the bottom of the IC case and a
rasied pad on the heatsink that fits into the depression. I've never seen
anything like this before! Note the delay line (?) on the LH side of the
card. Sorry I couldn't get a better picture. This is as close as I could
get with my camera.
Joe
